SANITARY SEAT FOR INVALID CHAIRS.

Application filed July 23, 1927. serial No. 207,962;

My invention relates to improvements in sanitary seats for invalidchairs, and it consists in the combinations, constructions andarrangements hereinafter described and claimed.v 1

An object of my invention is to provide a sanitary seat for invalidchairs which is upholstered so as to provide a comfortable seat for thepatient, and in. which the central swingable portion is also upholsteredso as to provide a seat having auniformly level surface throughout itsentire area when the central portion is in closed position.

A further object of my invention is to provide a novelly constructedhinge for permitting the central portion to be swung into open positionand then to be moved laterally away from the opening. I

Other objects and advantages willappear in the following specification,and the novel features of my invention will be particularly pointed. outin the appended claim.

My invention is illustrated in the accompanying drawing forming a partof this application, in which Figure l is a vertical section throughthedevice Figure 2 is a view similar'to Figure 1, but showing thecentral portion in open position; and V Figure 3 is asection along theline 33 of Figure 1.

In carrying out my invention I provide a chair indicated generally at 1which has a seat portion 2, legs 3, a back 4:, and arms .5. The seat 2is provided with upholstering 6 andlias a swingable central portion 7which is likewise upholstered as at 8, whereby the seat resembles theuniformly upholstered seat when the central portion is closed.

Reference-to Figure 8 shows that the cen tral portion 7 is pivot-allysecured to the seat 2 by hinges 9. These hinges have slots 10 thereinwhich receive guide and supporting screws 11. WVhen the central portion7 is swung downwardlyit may be moved laterally, the screws 11 sliding inthe slots 10 for perinitin this movement. The central portion 7 is ieldin closed position by means of a retractable bolt 12.

From the foregoing description it will be seen that the chair isespecially designed fir permitting an invalid to sit up during thedaytime instead of being confined to the bed.

When the central portion 7 is closed the chair inall respects resemblesa standard one; The central portion 7 will swing by gravity whenreleased by the bolt' 12, and after swinging into a vertical position itmay be moved into the position shown in Figure 2.

A container 13 may now be placed upon supporting bars 14 or disposedupon the floor if desired. Y

lVhere the invalid is helpless it isoftentimes necessary to apply forcetothe central portion 7 in order to close the portion and to lock it inclosed position. In order to more effectively close the central portion,I mount an eyelet 15, (see Figure 3 on the central portion and use a rod16, shown by the dot upon thecentral portion 7 of sufiicient force formoving the portion back into closed position even though this movementnecessitates ted lines in Figure 1, for creating a leverage The rod 16is inserted After the central portion has been closedit J is a simplematter to slide the bolt 12 into operative positionv for locking thecentral portion in closed position. I

The device is extremely simple in construction and materially alds anurse in car- 'ing for an invalid, and also permits an'invalid to sit upduring the daytime, where normally a patient would be compelled toremain in bed all day.

Although I have shown and described one embodiment of my invention, itis to be understood that the same is susceptible of various changes andI reserve the right to employ such changes as may come within the scopeof the appended claim. I claim: An invalid chair having a centralopening therein," a central portion removably dis-Y posed in saidopening, hinges securing said portion to said seat for permitting'saidpor-- tion to swing downwardly whencreleased, said hinges beings'lidably connected to said seat for permitting said portion to be movedlaterally away from said opening after said portion has been swungintoopen position.
